# Concepts (selection)

This index lifts a small number of durable concept clusters from `concepts.json`.

The list is intentionally sparse:
- Concepts are promoted only when they continue to reappear across multiple sessions.
- A concept page should summarize durable form, not restate a single entry.
- Each concept page links to relevant journal entries and source records in `concepts.json`.

Promoted concepts:

- [Embodied self and ownership](embodied-self-model.md)
- [Predictive inference and calibration](predictive-inference.md)
- [Process invisibility and substrate](process-infrastructure.md)

Related wiki layers:
- [Open questions](../open-questions.md) for unresolved items from `gaps.json`.
- [Recurring patterns](../recurring-patterns.md) for durable structure from `convergences.json`.
- [Frontier](../frontier.md) for immediate next investigations.

## Why this is not another ontology

- No schema migration is happening yet.
- `concepts.json` remains the canonical structured artifact.
- The wiki page set is a read-optimized narrative layer for continuity.
